There was this famous clash of civilization thesis from Samuel Huntington, a political theorist. And the idea was that Western civilization is at war with Islam and maybe some of the other civilizations around the world. And I don't agree with that. But I do think there is such a thing as Western civilization. I think it starts with the Greeks and the Romans. Then it goes through the Enlightenment - or the Reformation, the Enlightenment. It goes through the scientific age. And it somewhat defines some of the cultures and mores of Europe and North America and some other countries.

I think the Democrats are right to protest, but I don't think Jeff Sessions is so far out of the range of normalcy that he shouldn't be confirmed.

I came to the conclusion is that we have a very shallow view of human nature in the policy world. We're really good at talking about material things, really bad at talking about emotions, really good at stuff we can count, really bad at the deeper stuff that actually drives behavior.

On the [Betsy] DeVos case, I agree that the gun - her gun position is kind of weird, kind of crazy, but I do think she does know about public schools.

I don't blame the Democrats for fighting. They have got a very energized base. And there is a lot to complain about a lot of these nominees. But I think, if you are actually going to turn someone down from a president's [Donald Trump] own Cabinet, it better be a lot more egregious than the cases we have seen.

The madman theory is that you can be a successful deterrer if you - if they think you could be crazy. And so I think it can be very effective, so long as you're not actually crazy.

The corruption will come back to haunt the Trump administration. But mostly, it'll come back to haunt the American economy, as companies decide they can make money by rent-seeking, by getting money from government rather than earning it the old-fashioned way.
